"What's the typical transmission speed for UAVCAN?"

"This is encouraging. It shows that it is possible.

In large scale industrial systems I've seen that it's very normal that the "designer/developer" can make his machine work "to perfection". But anyone else can quickly find the bugs, or can't easily…"

"I just came back from another test with my X8 and 3.2.1. I started by taming down the gains, they were at autotune values from a 3.2 autotune.

This test was with standard X8 gains plus ATC_ACCEL:RP_MAX at 72000, ATC_RATE_RP_MAX at 18000 and…"

"I'm sure my X-8 is worse with this, and right now it has 3.2.1 on it. My IRIS has 3.3rc5. So I'll test with the same firmware on both and try to get the parameters as close as possible.

Sorry about the Loiter braking comment. I haven't used Loiter…"

"Ahhh-Haaa. Great!  So it behooves us to be the first to resolve this.

My bigger X-8 behaves similarly to the video they show there. All very familiar. I did manage to improve it with some adjustments, but just got it down to 2 or 3 m drops. They…"

"It's really quite a complex issue (nonetheless important).
The theme was looked at fairly intently. In the end investigations basically proved that it IS an aerodynamic effect of pressure modification in a bubble around the craft. One would think…"

"To be honest, I just came back from a short test (6 min) comparing poshold and loiter.

Everything worked perfectly!! Go figure?? It's a pretty calm day though, it's incredible what a bit of wind can do.

I'm using 3.3rc5 right now. Since I really…"

"Hi Leonard,

I seem to remember that among the claims of poshold, was it's abibility to close the gap between Loiter, and the parallel funtionality the DJI offered. I'd really have to go back and search the files to get the details, but the main…"

"Perhaps this is something that follows cycles. For instance the move to 3.2 was a big one and involved many new features and improvments. And these are necesary, to compete, to provide long required safety features, stability etc.

But once a major…"

"A couple more tests on the bench.

As suspected, once the unit warms up, a power reset shows less altitude deviation, it only climbs to about a meter in a couple of minutes and stabilizes. But it doesn't reset on ARM."

" A bump on my problem of 12 hrs ago.

I see that the altitude drift after  initial  boot isn't reset on arming. Is there something new there?

Yesterday, I took off from +3m and landed at 9m. This would affect autoland. (in this case I did a manual…"
